Peavey Studio Pro 112 - Manual (Page 9)

21. External Speaker Jack
This 1/4" jack is provided for the connection of an external speaker cabinet such as the
Peavey 412M. The minimum external speaker impedance is 8 ohms. This jack disconnects
internal speaker when used on Studio Pro 112
NOTE: The remaining features apply to the Bandit 112 model only.
22.
Preamp Out
The Preamp Output can be used to route the preamp signal to a mixing console, tape
recorder, etc. Using a shielded instrument cable with mono 1/4" plugs, connect the Preamp
Output to the input of your outboard equipment. This patch will not affect the normal operation
of your amplifier.
23. Power Amp In
Connect line level signals from external equipment to this input. Inserting a plug into this
mono 1/4" jack will prevent the TransTube preamp signal from being sent to the amplifier.
In this configuration, the power amp only amplifies the signal introduced at the Power Amp
In jack.
24. Effects Level
This switch selects the Effects Loop (20) operating level. When the switch is pressed to the
“in” position the level is set for 0 dBV (1 V RMS). Placing the switch to the “out” position
changes the level to -10 dBV (0.3 V RMS). Refer to the owner’s manual for your external
effects to determine the correct position for this switch.
25. Ground Switch
Place this switch in the center position (0) during normal operation. If audible hum occurs,
position the ground switch in either the positive (+) or negative (-) position to minimize the
noise. You may have to try both positions to see which is more quiet.
NOTE: Should the noise problem continue, consult an Authorized Peavey Dealer or Peavey
Repair Center. THE GROUND SWITCH IS NOT FUNCTIONAL ON 220/240 VOLT MODELS.
